Abstract
The present disclosure provides a pair of NMOSFET switches connected in series, an output filter, a control circuit, a boot-strap capacitor and a disabling circuit. A high-side MOSFET switch is coupled to an input voltage. A low-side MOSFET switch is coupled to a ground. The high-side MOSFET switch and the low-side MOSFET switch have complementary duty cycles. The output filter is coupled to the NMOSFET switches to provide an output voltage. The boot-strap capacitor is coupled to the source of the high-side MOSFET switch. The voltage crossing the boot-trap capacitor is for making the gate voltage of the high-side MOSFET switch to be higher than the input voltage. The disabling circuit senses the voltage crossing the boot-strap capacitor, and generates a control signal to control the control circuit for continuously turning off the high-side MOSFET switch when the voltage crossing the boot-strap capacitor is less than a threshold voltage.
